Blade edge is wave shape. Used for cutting cardboards. The cut cardboards can be carried safely (the Product Liability Law).

FORM PERFORATING RULES

16H in height. For lateral perforating.

PERFORATING CREASING RULES

0.45×23.0/23.4. For lateral perforating

CREASING RULES (IRON)

Not hardened

SPECIAL CREASING RULES(STEEL)

Hardened

SPECIAL CREASING RULES(STEEL)(Dull Point)

Hardened edge is rounded at a sharp angle.

CUT CREASE RULES

Cut and crease are alternately arranged; best for acute-angled folding

Hi-MIR

The edge of PET (30H or more) is mirror-finished.

NC Series adopt special steel with superior durability, bending workability and stability in the same bending work. Blade edges that are sharpened with a grinding wheel made of fine abrasive grains have unparalleled sharpness. These edges(normally 0.3 mm from the blade tip), processed by high-frequency hardening to achieve high hardness of HS70 - 80
(HV550 - 680/HRC52.3 - 59.2), are less-wearing and maintain sharpness, thus ensuring a high volume of punching and creating a large quantity of punched products with smooth surfaces.

STANDARDS OF NAKAYAMA’S CUTTING RULES

STANDARD BEVELS

* The above are standard bevels (Thickness of 0.7 mm).
* Bevels with different shapes and edge angles other than above are also available.

STEEL TYPE

Application

Steel type

Bendable

S50C

Durable (Unbendable)

SK85

Resistant to corrosion

SUS

The specially-hardened material forms a surface-softened layer and is highly bendable.

THICKNESS

We only use steel sheets manufactured by our reliable contractor, which meet our own thickness tolerance standard.
The thickness difference between the points T1 and T2 is less than 0.005 mm.

HEIGHT

Bevels of the CUTTING RULES are sharpened with a special grinding wheel made of fine abrasive grains. Height and edge angles are measured by the grinding machine in real time, controlling them in micrometer. Based on the processing information printed by lot, we only ship the products within the height tolerance range.

HARDNESS AND WIDTH OF SURFACE-HARDENED LAYER

Body hardness：

HS (Shore hardness)
40／45／50／55／60／65／70／72

Edge hardness：

HS (Shore hardness)
65／70／72／75／80

Width of surface-hardened layer：

Width of surface-hardened layer: 0.3 mm (from the blade edge) for the regular product; products with width of 0.2 - 0.5 mm are also available according to your need.
